Hi Charlie,
As a way of assessing the level of effects the compaction etc is having on 
the root system, can I suggest you dust off an old bit of kit, and take an 
increment core from the affected side of the tree - from a 'neutral point' ie 
not above a buttress or cleft, where the annual increment might be expected 
to be average for the tree; and do the same on the unaffected side.  You'll 
only need to take a core perhaps 100mm long; then extract the cores, plane or 
smooth them carefully with a very sharp chisel on the upper or lower surface 
- ie at right angles to the fibres - and have a look at the annual increment, 
especially the width of the rings shown.  If there is a variation between 
sides, or if the increment has decreased steadily or suddenly since the date 
of the compaction from the rebuild, that will tell you a lot about how the 
tree is managing.
Takes practice, but gives you the equivalent of a time machine going back to 
see how the tree has grown over the years.  I don't know where you are 
posting from, but if it is somewhere in the dry SE of UK, you'll need to 
factor in drought years etc as well, as climate affects increment - which is 
what dendrochronology is based on, after all...

All the best
Rupert

Subject: Another big Beech to care for.

Hello All,

I have a client with another very large Beech with a partially compacted 
rooting area (caused by excessive traffic for the type of surface, some 
surface root damage and some fungal fruiting bodies of possibly honey fungus 
(rotted down so difficult to tell).  Stem is sound, crown is stunningly 
perfect. Owners are aware of risks and would like to maintain tree for as 
long as possible.

Ideally I’d like to arrange decompaction/aeration, root investigation, 
mulching, create a new driveway surface (including cellular system and 
permeable surface) and create an aesthetically pleasing barrier to stop 
traffic cutting the corner again and causing direct damage to the exposed 
roots.  Majority of traffic has already been diverted, but some access to the 
rear of the property is still required (I did suggest moving it all but that 
was a step too far).  

In the long term I have warned that systematic retrenchment may be required 
as well as the above, though I am loathe to do this to a beech and such a 
fine specimen.

I ask for any sources of information, guidance, or research on similar cases. 
 Also, of any contacts for advice or the decompaction, aeration and root 
investigation that cover the north west of England.  

And of course if there is something that I may not have mentioned as a course 
of action you feel would be pertinent in saving this ‘big Ol’ girl’ from past 
poor management, please do let me know.


Best Wishes
Charlie
